223003431 - E7030 AIR BAG - FUNCTIONAL DESCRIPTION (MY 2005)

The control unit for the Air Bag system M60 receives a supply controlled by the ignition (INT) at pin 8 of connector A from the line protected by fuse F50 of the junction unit under the dashboard B02.Pin 16 of connector A of M60 is earthed.When, on the basis of the control logic, a side impact of a certain severity is detected, the Air Bag control unit M060 (connector B) sends signals for the intervention of the modules:- Driver''s sidebag Q30 (from pins 23 and 24);- Passenger sidebag Q31 (from pins 21 and 22);The cases of Air-Bag sidebag modules Q30 and Q31 are earthed.when driver''s side impact detection sensor K66 and passenger''s side impact detection sensor K67 detect impacts of a certain severit, they send signals to control unit M60 at pins 10 and 9 of connector A.Early Crash sensor K175 located on the front part of the vehicle near the radiator is connected to pin 4 connector A of M60.When, on the basis of the control logic, a side impact of a certain severity is detected, the Air Bag control unit M60 sends signals for the intervention of the modules:- Driver''s side front Air Bag Q09 (from pins 21 and 22 connector A);- Passenger side front Air Bag Q11 (from pins 23, 24 and 20, 19 connector A);- front driver side pretensioner Q20 (at pins 9, 11 connector B);- front passenger side pretensioner Q21 (at pins 10, 12 connector B);The control for exclusion of passenger side Air Bag H75 is connected to control unit M60 at pins 5 and 6 of connector A.If the passenger air bag is disabled, control unit M60 sends a signal from pin 15 connector A to instrument panel E50 (pin 14 connector B) to turn on the warning light.''When the system self-diagnosis detects a fault or if an impact occurs, control unit M60 sends a signal (from pin 11 of connector A) to turn on the airbag system fault warning light located in instrument panel E50 (pin 13 of connector B).Control unit fault diagnosis may be carried out by connecting to conector B pin 3 of body computer M01. This signal (K line) is received from pin 7 of connector A of control unit Air-Bag M60.    See E8010 DIAGNOSTIC MULTIPLE CONNECTORThe body computer M01 receives a supply controlled by the ignition and a direct supply at pins 11 of connector E (INT)and pin A of connector C, respectively for the junction unit under the dashboard B02.Fuse F1 in engine compartment junction unit B01 protects the direct power supply.These lines also supply control panel E50 pins 1 and 3 of connector A (for the Natural Power version - 1596 16V BPW - , pins 1 and 2 connector A) by splitting inside under-dashboard control unit B02.These lines are protected by fuses F37 and F53 of B02.Pins 8 and 9 of connector D of body computer M01 are earthed. This reference earth is also supplied to panel E50 at pin 2 connector A (for the Natural Power version - 1596 16V BPW - , pin 7 connector A) via pin 36 connector F of the body computer.Seat belt control unit M48 emits a buzzer to remind the driver to do up the belt before setting off.Control unit M48 – pin 2 - is supplied with an ignition-controlled supply (INT) via belt buzzer bypass switch J146 via a line protected by fuse F49 of under-dashboard junction unit B02. Pin 1 of M48 is earthed.Body Computer M01 supplies - pin 23 of connector E - a speedometer signal generated by sensor K84 (pin 17 of connector C of M01), at control unit M48 – pin 4 -.Seat belt control unit M48 receives at pin 1 an earth signal from driver side seat belt switch I46. If the seat belt is unfastened a signal leaves pin 3 of M48 to turn on a flashing seat belt unfastened light on instrument panel E50 (pin 15 of connector B) together with a buzzer.If reverse is engaged (by means of reversing switch I20), seat buzzer bypass switch J146 is activated and cuts off power to control unit M48 to bypass the signal device.
